So i recently ordered a refurbished MBP 13 incher, with base items however i was planning on swapping out HD/Ram w/e to like 500 and 4GBs, now should i cancel my order and get a new MB or should i stick with my order and keep the Refurbished MBP 13. And one more question does apple ship at various times of the day or do they ususally ship everything at one time. ( since its refurbished i also assume it ships within the US?)
